I suppose the only parallel which does occur is people with serious mental health issues being sectioned.
Yes, because of their potential to harm others. Being suicidal isn't enough to get you sectioned, you have to be a clear danger to others.
It’s a tough one. If a professional psychologist identifies someone as being dangerous and a potential axe murderer should we wait for them to do it before acting or should we just lock them up just to be safe even if they’ve so far done nothing?
We're not talking about locking this guy up. We're talking about the equivalent of not letting a potential axe murderer have an axe.
After the Dunblane school shooting, around 10,000 law-abiding shooters had their pistols confiscated by the Govt and section 5 of the Firearms Act was amended to ban private ownership of most pistols. Few people outside the shooting community consider that ban disproportionate, yet many on this thread think that banning one man, who already has form for sexual harassment and does not understand the need for consent and this lack of understanding is supported by observational evidence, from having unsupervised access to women is disproportionate to protect an unspecified and potentially unlimited number of women.
No one seems to want to engage with the fact that he already has form for boundary violations. No one seems to want to engage with the reality that, to have sex (which the ruling was explicitly about), a man, who is known not to understand the need for a woman to consent, will have to be left alone and unsupervised with a woman.
He can have supervised dates, supervised nights out, supervised everything, but not supervised sex. And sex is when he is the most danger to women. Sex is when he most needs to understand the need for the woman's consent. And he doesn't. And the only way to give him that access is to knowing put women at elevated risk of rape.
